N Campbell updated DRILL-5620:
------------------------------
Description:
Calcite's parser documentation indicates that it has provided for
aggregate(<exp>) FILTER.
This construct is not supported by many vendors, hence it such a statement is
expressed to Drill against a plugin mapped to JDBC it may fail due to the
statement being push down (i.e. to ORACLE). But the operation will
parse/execute when performed locally on dfs etc
select count( CINT ) filter ( where RNUM > -1) from x.y.z
DATA_READ ERROR: The JDBC storage plugin failed while trying setup the SQL query
Looks like it tries to emit SELECT "CINT", "RNUM" > -1 "$f1" FROM X"."Y"
